The present invention provides an LTE wireless communication air interface protocol software self-test device and method, which configures the user equipment bearer parameters of the first protocol software processing module and the second protocol software processing module, waits for the air interface data transmission cycle T to arrive, and sends N data packets Go to the internal protocol layer processing of the first protocol software processing module, simulate the air interface wireless environment, randomly discard or change the data packets processed by the internal protocol layer of the first protocol software processing module according to the simulated air interface wireless environment, and send processing The final data packet is processed to the internal protocol layer of the second protocol software processing module, and the data correctness verification is performed on the data packet processed by the internal protocol layer of the second protocol software processing module. Simple and realistic simulation of air interface wireless environment and test protocol software data processing application scenarios, the stability of LTE wireless communication air interface protocol software is found through self-test in the early stage of development, ensuring the reliability of the software.
Description
technical field [0001] The invention relates to the technical field of wireless communication, in particular to a software self-test device and method for LTE wireless communication air interface protocol. Background technique [0002] LTE wireless communication air interface protocol includes PDCP layer (Packet Data Convergence Protocol, packet data convergence protocol layer), RLC layer (Radio Link Control, radio link control protocol layer) and MAC layer (Media Access Control, media access control protocol layer), Among them, PDCP is responsible for functions such as data header compression / decompression, integrity protection, encryption / decryption, PDCP SN value maintenance, sequential delivery, and timing discard; RLC is responsible for TM (transparent mode), UM (unacknowledged mode) and AM ( Acknowledgment mode) three modes of data transmission, RB (Radio Bearer, radio bearer) entity data segmentation, concatenation and reassembly functions; MAC is responsible for logi...
